obstructive lung diseases

Question 1

types of lung diseases

Answer 1

Obstructive: air goes in and cant go out easily, air trapping and hyperinflation, reduced FEV1/FVC ratio

Restrictive: lung very scarred so air cant get in easily, Low TLC, normal FEV1/FVC ratio

Combo: recent addition of asthma-COPD, ILD-COPD groups

Question 2

Pulmonary function testing

Answer 2

process of having the patient perfom specific inspiratory and expiratory maneuvers, compared to predicted normal values

Question 3

indications for pulmonary funtion testing

Answer 3

Evaluate symptoms, signs, abnormal lab tests, assess the effects of diseases and therapies on the respiratory system
Screen at risk people for pulmonary disease, preop risk, prognosis

Question 4

Indications for spirometry

Answer 4

monitoring- assess therapeutic intervention, describe the course of diseases that affect lung function, monitor people exposed to injurious agents, monitor for adverse reactions to drugs with known pulmonary troxicity
Disability/impairment evaluations

Question 5

Info used to obtain predicted values

Answer 5

Height, weight, age gender, race/ethnicity

Question 6

Normal spirometry

Answer 6

test meets acceptability and reproducibility standards

FEV1/FVC is normal .7 to .87

Question 7

Restrictive ventilatory defect

Answer 7

Interstitial lung disease (sarcoidosis, colagen vascular diseases, pulmonary fibrosis)
Pneumonectomy
pleural disease: pleural effusion
Chest wall disease: kyphosis, neuromuscular disorders
Extrathoracic conditions: obesity

Normal FEV1/FVC ratio, and a decreased FVC
Interpret cautiosly from spirmetry

REDUCED TLC IS THE TRU HALLMARK

Question 8

Obstructive Ventrilaroy pattern

Answer 8

Large conducting airways: tumors, foreign bodies, peripheral airways asthma, chronic bronchitis
